951EN, 952EN: Ethernet Analog and Discrete I/O Modules

951EN, 952EN: Ethernet Analog and Discrete I/O Modules Description

951EN: Combo module, analog current inputs
952EN: Combo module, analog voltage inputs

These Ethernet analog and discrete I/O modules provide an isolated Ethernet network interface for analog and discrete I/O signals. Multi-range analog inputs and outputs support a wide variety of industrial devices.

High-resolution, low noise, A/D and D/A converters deliver high accuracy and reliability. 3-way isolation further improves system performance. The discrete I/O provide monitoring and control of on/off, high/low, or open/close industrial devices.

Tandem I/O provides output level control and status verification in one unit.

The i2o function lets inputs on one module write directly to outputs on another module. Available for Modbus TCP/IP communication only. Read more about peer-to-peer i2o function.
